⭐前言

在本篇博客中，我们将介绍如何使用 HTML、CSS 和 JavaScript 创建一个包含数字时钟和搜索功能的简单网页。这个网页不仅具有现代的外观，还能实时显示当前时间，并允许用户输入搜索内容。

⭐一、项目结构

我们的项目结构如下所示：

复制代码

test
    ├── index.html
    ├── myCss.css
    └── myJsp.js

index.html：主页面文件，包含 HTML 结构和基本样式。
myCss.css：自定义样式文件，用于美化页面。
myJsp.js：JavaScript 文件，负责实现时钟和搜索功能的逻辑。

⭐二、HTML 结构

在 index.html 文件中，我们首先定义了基本的 HTML 结构。我们使用了 Bootstrap 框架来快速构建响应式布局。以下是主要的 HTML 代码片段：

html 复制代码

<!DOCTYPE html>
<html lang="zh-CN">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta name="description" content="XX科技公司 - 领先的软件开发解决方案提供商">
    <title>XX科技公司 | 创新驱动未来</title>

    <link href="https://lf3-cdn-tos.bytecdntp.com/cdn/expire-1-M/font-awesome/5.15.4/css/all.min.css" rel="stylesheet" type="text/css">

    <link rel="stylesheet" href="myCss.css">
</head>
<body>
<i class="fas fa-ellipsis-v uil uil-ellipsis-v dot-menu-btn" style="color:#fff" id="active-menu"></i>
<ul class="dot-menu" id="active-menu">
    <li class="menu-item" id="active-menu">
        <span class="clock-format-text" id="active-menu">24-Hour Format</span>
        <div class="format-switch-btn" id="active-menu" date-format="12"></div>
    </li>
</ul>

<div class="container">
    <div class="row height d-flex justify-content-center align-items-center">
        <div class="col-md-8">
            <div class="search">
                <i class="fa fa-search"></i>
                <input type="text" class="form-control" id="search-input" placeholder="Have a question? Ask Now">
                <button class="btn btn-primary" id="search-button">Search</button>
            </div>
        </div>
    </div>
</div>

<div class="time">
    <span class="hours">00</span>
    <span class="dots">:</span>
    <span class="minutes">00</span>
    <div class="right-side">
        <span class="period">AM/PM</span>
        <span class="seconds">00</span>
    </div>
</div>

<div class="calender">
    <span class="month-name">Month</span>,
    <span class="day-name">Day</span>
    <span class="day-num">00</span>
</div>

<script src="myJsp.js"></script>
</body>
</html>

⭐三、CSS 样式

在 myCss.css 文件中，我们使用了一些 CSS 来美化页面的外观。以下是一些关键的样式：

css 复制代码

@import url("https://fonts.googleapis.com/css2?family=Poppins:weight@100;200;300;400;500;600;700;800&display=swap");

    background: #0bff8d;
    box-shadow: 0 5px 25px #0bff8d;
    transform: translateX(10px);
}

⭐四、JavaScript 功能

在 myJsp.js 文件中，我们实现了数字时钟和搜索功能。以下是相关的 JavaScript 代码：

javascript 复制代码

//js for switch clock format

const formatSwitchBtn = document.querySelector(".format-switch-btn");

formatSwitchBtn.addEventListener("click", () => {
    formatSwitchBtn.classList.toggle("active");

    var formatValue = formatSwitchBtn.getAttribute("date-format");

    if (formatValue === "12") {
        formatSwitchBtn.setAttribute("date-format", "24");
    }
    else {
        formatSwitchBtn.setAttribute("date-format", "12");
    }
});


//Get Current Time In Javascript
function clock() {
    var today = new Date();

    var hours = today.getHours();
    var minutes = today.getMinutes();
    var seconds = today.getSeconds();
    let period = "AM";

    //set the time period
    if (hours >= 12) {
        period = "PM";
    }

    //set 12 hour clock format
    var formatValue = formatSwitchBtn.getAttribute("date-format");

    if (formatValue === "12") {
        hours = hours > 12 ? hours % 12 : hours;
    }




    //add 0 for the value lower than 10
    if (hours < 10) {
        hours = "0" + hours;
    }

    if (minutes < 10) {
        minutes = "0" + minutes;
    }

    if (seconds < 10) {
        seconds = "0" + seconds;
    }


    document.querySelector(".hours").innerHTML = hours;
    document.querySelector(".minutes").innerHTML = minutes;
    document.querySelector(".period").innerHTML = period;
    document.querySelector(".seconds").innerHTML = seconds;
}
var updateClock = setInterval(clock, 1000);

// get the date in js

var today = new Date();
const dayNum = today.getDate();
const year = today.getFullYear();
const dayName = today.toLocaleString("default", { weekday: "long" });
const monthName = today.toLocaleString("default", { month: "short" });

document.querySelector(".month-name").innerHTML = monthName;
document.querySelector(".day-name").innerHTML = dayName;
document.querySelector(".day-num").innerHTML = dayNum;
// document.querySelector(".year").innerHTML = year;

//js for dot menu toglle

const dotmenuBtn = document.querySelector(".dot-menu-btn");
const dotMenu = document.querySelector(".dot-menu");
dotmenuBtn.addEventListener("click", () => {
    dotMenu.classList.toggle("active");
});

document.addEventListener("click", (e) => {
    if (e.target.id !== "active-menu") {
        dotMenu.classList.remove("active");
    }
});

// 添加搜索按钮的点击事件
document.getElementById("search-button").addEventListener("click", function() {
    var searchInput = document.getElementById("search-input").value;
    if (searchInput.trim() === "") {
        alert("请输入搜索内容！");
    } else {
        alert("您搜索的内容是: " + searchInput);
    }
});

⭐五、运行效果

调整时间格式：

按钮提交提示：

⭐总结

通过以上步骤，我们成功构建了一个包含数字时钟和搜索功能的网页。用户可以在输入框中输入问题并点击搜索按钮，页面会弹出提示框显示用户输入的内容。同时，数字时钟会实时更新，显示当前的时间。

这个项目展示了如何结合 HTML、CSS 和 JavaScript 创建一个简单而实用的网页应用。希望这个示例能为你的网页开发之旅提供灵感！
